New service taps users to help filter Internet sites

NEW YORK &#8212; You can now help decide what Web sites your boss should block.

A new service from OpenDNS lets users tag sites under categories such as &quot;gambling,&quot; &quot;hate&quot; and &quot;social networking.&quot; Others can weigh in on whether they agree with those classifications. If there are enough votes, the site gets added to a system used by companies, schools and other organizations to block access.

OpenDNS says its approach is better than commercial software because more people are reviewing sites and can do so quickly as new ones pop up.

OpenDNS already has a filtering system for &quot;phishing&quot; scam sites using a similar, community-based approach. It contracts with a vendor, St. Bernard Software, to filter pornography sites, and those sites will not be part of the new tagging program.

The system is free to use. The filters are part of OpenDNS' main service providing the directories necessary to translate a Web site's domain name into its actual numeric Internet address. OpenDNS estimates it has more than 4 million users worldwide.

Marjorie Heins, founder of the Free Expression Policy Project research group, worried that &quot;one ideological group can impose its tastes and ideas by stuffing the digital ballot box and labeling content that other users of the system might not think is objectionable.&quot;

OpenDNS says it has a built-in trust mechanism, giving more weight to users who have submitted accurate tags more often in the past than those who have submitted fewer tags or have never done so.
